Burling Hull (September 9, 1889 - November 1982) was an inventive magician, self-styled "the Edison of magic," specializing in mentalism and sleight of hand effects. During the greater part of his life he lived in DeLand, Florida. His aliases and stage names included: "Volta the Great", "The Man with the Radar Mind", "The White Wizard," and "Gideon ('Gid') Dayn."
Hull claimed to be — and is generally credited as — the inventor of the Svengali deck of cards, which he patented in 1909. He claimed to have invented more than 500 magical effects and he was a prolific writer, with 52 published books to his name, including Sealed Mysteries and Sleights, The Encyclopedia of Stage Illusions, Sealed Mysteries, and How to Answer Questions for Crystal Gazing and Mind Reading Acts. He wrote on a wide variety of magical subjects, including card tricks, mentalism, escapes, razor blade swallowing, sightless vision, billiard ball manipulation, silk magic, second sight acts, publicity, and showmanship.
Hull not only produced many titles about magical effects, he also performed and taught magic for more than 80 years. In his earlier "White Wizard" years, he performed an act dressed entirely in white in which he made billiard balls and silks vanish, multiply, and reappear. In later years he gave talks to magic conventions on business methods for entertainers.
Hull was active in the movement to recognize that there are intellectual rights to magic methods and he was a strong advocate for the protection of magic trade secrets by both patents on the gimmicks and copyright on the texts, as applicable. However, he undercut his own ethical stance against plagiarism by publishing secret material from other magicians who had stolen ideas from him, in order to get revenge for having been plagiarized. 
In the late 1950s Hull published a newsletter, The G_d D__n Truth About Magic, mainly for the purpose of criticizing the equally famous mentalist Robert A. Nelson, known on stage as "Korda RaMayne." Hull used the pseudonym Gideon ("Gid") Dayn to expose Nelson's effects under the pretense of "reviewing" them.
Hull's weighty three-volume Encyclopedic Dictionary of Mentalism, published in 1961, was the largest compilation of mentalism sleights, gimmicks, effects, patter, and illusions in one collection up to that date. This work was also notable as the venue in which Hull continued to carry out his excoriating feud with Robert Nelson, whom Hull accused in print of teaching mentalism to gamblers and racketeers in order that they might commit what Hull called "thievery of the public." He also criticised Nelson for selling hoodoo folk magic curios that Hull said were used in rituals of "black magic and Devil worship".
In his final years, Hull lost his eyesight, a loss he never learned to accept. He died at the age of 93 in a nursing home. Hull's life and his impact upon the world of stage magic were described in a 1977 biography, The Edison of Magic and His Incredible Creations, written by Samuel Patrick Smith. Both his Svengali Deck of 1909 and his 33 Rope Ties and Chain Releases, written in 1915, are still popular today.
